Description:
------------
An Query String with "=" at the end deletes all other GET variables (empty $_GET array).
Seems to be related to the following bugs, but as far as I can see this server does not run Apache2 and suPHP (?).

This problem occured on three of our client's server.
I can provide the complete output of phpinfo() if needed.

Reproduce code:
---------------
Open get.php?key=val&foo= in your browser.
Notice the "=" at the end.
-- get.php --
<?php
var_dump($_GET);
?>

Expected result:
----------------
array(2) {
  ["key"]=>
  string(3) "val"
  ["foo"]=>
  string(0) ""
}

Actual result:
--------------
array(0) {
}
